Indlela yokuphucula ukuchaneka kweembumba zeplastiki?
1. Umgangatho wokulungisa umngundo ubandakanya ukuchaneka kokulungiswa kunye nomgangatho womphezulu
Ukuchaneka komatshini yinqanaba lokuhambelana phakathi kobukhulu bokwenene, imilo kunye nesikhundla somphezulu wecandelo lomatshini kunye neeparitha ezifanelekileyo zejometri ezifunwa ngumzobo.
Iparameter yejometri efanelekileyo, kubungakanani, ubukhulu obuphakathi; Kwijometri yomphezulu, sisangqa esipheleleyo, isilinda, indiza, ikhowuni kunye nomgca othe ngqo. Kwindawo ehambelanayo phakathi kwemiphezulu, ihambelana ngokupheleleyo, ime nkqo, i-coaxial, i-symmetric, njl njl.
Ukuchaneka komatshini kunye nephutha lomatshini zombini amagama asetyenziselwa ukuvavanya iiparameters zejometri zeendawo ezinomatshini. Ukuchaneka koMatshini kulinganiswa ngebakala lokunyamezela, elincinci ixabiso lebakala, ukuphakama kokuchaneka; Impazamo yomatshini ibonakaliswa ngexabiso lamanani, kwaye ixabiso lamanani likhulu, impazamo enkulu. Ukuchaneka okuphezulu kokusebenza kuthetha impazamo encinci yokucubungula, kwaye ngokuphambeneyo.
Iiparamitha zangempela ezifunyenwe yiyo nayiphi na indlela yokucubungula ayiyi kuchaneka ngokupheleleyo, ukusuka kumsebenzi wecandelo, nje ukuba impazamo yokucubungula ingaphakathi kokunyamezela okufunwa ngumzobo wenxalenye, ukuchaneka kokucubungula kuthathwa njengokuqinisekiswa.
Umgangatho womatshini uxhomekeke kumgangatho womatshini wamacandelo kunye nomgangatho wendibano yomatshini. Umgangatho womatshini wamacandelo uquka ukuchaneka komatshini wamacandelo kunye nomgangatho ophezulu wamacandelo amabini. Ukuchaneka komatshini kubhekiselele kwiqondo apho iiparameters zejometri zangempela (ubukhulu, imilo kunye nesikhundla) samacandelo emva kokucubungula zihambelana neeparitha ezifanelekileyo zejometri.
Umahluko phakathi kwabo ubizwa ngokuba yimpazamo yomatshini. Ubungakanani bempazamo yomatshini bubonisa ukuchaneka komatshini. Okukhona impazamo inkulu, kokukhona isezantsi ukuchaneka komatshini, kwaye impazamo encinci, kokukhona iphezulu ukuchaneka komatshini.
2. Imiba ephambili echaphazela ukuchaneka kokucubungula
2.1 Ukuchaneka komgangatho
Ibhekisa kwiqondo lokuthotyelwa phakathi kobukhulu beyona nxalenye yomatshini kunye neziko lonyamezelo lommandla wesayizi yenxalenye. Ukuchaneka kweDimensional kulawulwa kukunyamezelwa kwe-dimensional. Ukunyamezela kwe-Dimensional ukuhluka okuvumelekileyo kubukhulu benxalenye ngexesha lokusika. Kwimeko yobukhulu obufanayo obusisiseko, incinci i-dimensional tolerance kwaye iphezulu ukuchaneka kwe-dimensional.
2.2 Ukuchaneka kobume
Ibhekisa kwiqondo lokuthotyelwa phakathi kwejiyometri yokwenyani yomgangatho owenziwe ngomatshini kunye nejometri efanelekileyo. Kukho izinto ezi-6 zokuvavanya ukuchaneka kwemilo, njengokuchaneka, ukunyameka, ukujikeleza, isilinda kunye neprofayili yomgca. Ukuchaneka kobume kulawulwa ngokunyamezelwa kwemilo, kwaye ukunyamezelana kwemilo nganye kwahlulwe ngamanqanaba angama-12 okuchaneka ngaphandle kwamanqanaba angama-13 okuchaneka okungqukuva kunye ne-cylindricity. Inqanaba 1 lelona liphezulu kwaye inqanaba le-12 lelona liphantsi.
2.3 Ukuchaneka kwendawo
Ibhekisa kumahluko kwindawo yokwenyani yokuchaneka phakathi kwemiphezulu echaphazelekayo yamalungu omatshini. Kukho izinto ezisibhozo zokuvavanya ukuchaneka kwendawo, ezifana ne-parallelism, i-perpendicularity, i-inclination, i-coaxiality, i-symmetry, indawo, ukuphuma okujikelezayo kunye nokuphuma ngokupheleleyo. Ukuchaneka kwesikhundla kulawulwa ngokunyamezelwa kwezikhundla, ezikwahlulwe ngokwamanqanaba angama-12 okuchaneka.
